EMERY E. CLARKgOF TOPEKA, KANSAS ROTARY RIDING MECHANISM Application filed. February 29,1928. Serial 1%. 257,963.

My invention relates to improvements in a rotary riding mechanism.

The object of my invention is to provide a rotor having an annular stationary mechanism arranged so that the peripheral portion thereof is in close proximity and in parallelism with the riding platform and having knobs peripherally positioned and equally spaced as pulling means for the occupants to cause rotation of the platform.

A further object of my invention is to provide a rotary riding mechanism that is inexpensive and simple to operate.

A still further object of my invention is to provide a rotary riding mechanism that is easily rotated so that one occupant is capable of actuating its movement, or a plurality of occupants may participate simultaneously in driving the mechanism. 7

A still further object of my invention is to provide a rotary mechanism that may be driven in either direction. 3

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawings forming a part of this specification, wherein like characters will apply to like parts throughout the different views.

. Referring to the drawings:

Fig. 1 is a plan view of the device.

Fig. 2 is an elevation.

' Fig. 3 is a sectional detail through the conicalportion.

The invention herein disclosed consists of an annular platform 1 having a conical portion 2 as concealing means for the framework to avoid possibility of entering beneath the mechanism, and being so arranged the mechanism is well braced and rotatably mounted on a center post 3, the said post having a foundation of concrete, as shown by dotted lines 4:. However, other means for supporting the post may be employed.

Positioned on the inner side of the platform is a polygonal railing 5 supported by upright members 6. Radially extending from the platform to the center is a plurality of rods 7 the inner ends of said rods are securely attached to a collar 8 that rotatably engages on the post. The said rods function as carrying means for the members 7 closing the space between said rods, the said'members being supported by a saddle 7 as shown in Fig. 3. The said railing 5 functions as a separating means between the platform and a disc plate 9 which is rigidly attached to the post 3 through the medium of a plate 10 that is integrally joined to a collar 11, having a threadedly engaging stud 12 as attaching means to the post. Peripherally positioned on the disc 9 and equally spaced apart are a plurality of knobs 13, which the occupant may grip and by pulling the same the platform is caused to rotate; at all times the knobs are convenient to the occupants participating in the actuating of the rotary movement of the platform.

While the disclosure shows the mechanism carried by a specially arranged foundation such as would be adaptable to playgrounds, it

will be understood, as heretofore stated, that other means for support may be arranged for the purpose of making the device portable, in which case the post may be supported by radially extending legs or a large disc like member. The mechanism being reduced in size for such an arrangement, is adaptable for nurseries or for a room in private homes.

Such other modifications may be employed as lie within the scope of the appended claims.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a rotary riding mechanism, in combi-- nation with a post, an annular platform having a railing at the inner margin thereof and rotatable therewith, the platform rotatably carried by the post, a disc rigidly attached to the upper end of the post, the peripheral edgeof the disc being in close proximity to the railing by which means an occupant of the platform may cause rotation thereof by pulling on the peripheral edge of the disc.

2. In a rotary riding mechanism, in combination with a vertically positioned post, an annular platform having apolygonal railing spaced upward from the platform and being carried by upright members spaced along the inner edge of the platform, the said platform rotatably carried by the post, a disc member rigidly attached to the post and being spaced a short distance above the railing, a plurality of knobs attached nearthe peripheral edge of the disc and being equally spaced therearound by which means an occupant of the platform Will cause rotation thereof by a tangential pull gripping the knobs, the rail ing functioning as a. guard for the occupant fromthe'peripheral edge of the disc.

In testimony WhereofI afliX my signature.
